Abstract
A structure for damping impact by mechanical deformation. The structure has an elongate shape in an impact direction and has a substantially constant cross-section. The structure includes longitudinal plates that form a central chamber and two lateral chambers disposed on either side of the central chamber. The lateral chambers each have a continuous exterior transverse contour. The central chamber has at least one pair of oblique longitudinal plates that are inclined oppositely relative to a plane of symmetry of the structurem, parallel to the impact direction.
